BIOS Setup
CPU Clock Ratio
This field is used to select the CPU’s frequency ratio.
Important:
• The frequency ratio of some processors may have been
locked by the manufacturer. If you are using this kind of
processor, setting an extended ratio for the processor will
have no effect. The system will instead use its factory default
ratio.
• The frequency ratio of processors greater than 8x has been
locked by the manufacturer and will no longer have the
flexibility of using extended ratios. Therefore, the system will
use the processor’s factory default ratio.
CPU N/2 Ratio
The options are Enabled and Disabled.
Target CPU Clock
This field will show the targeted CPU clock.
CPU Clock
This field provides several options for selecting the external system
bus clock of the processor. The available options allow you to adjust
the processor’s bus clock by 1MHz increment.
Important:
Selecting an external bus clock other than the default setting
may result to the processor’s or system’s instability and are not
guaranteed to provide better system performance.
Boot Up Clock
This field is used to select the boot up clock.
CPU Clock Amplitude
The options are 700mV, 800mV, 900mV and 1000mV.
